Students change their minds, majors, and career paths all the time. Many go into college not knowing their full range of options and passions. Some go in pushed by family since birth to follow a certain path (Be a doctor!) and then find their own voice and path.
I do think some get burnt out given the intensity of their high school experiences and the competition they feel to get into the “best” or most prestigious colleges.
Many of the top colleges and universities are big advocates of gap years. There are many benefits to taking a gap year and spending that time learning experientially but one of them is definitely getting off the hamster wheel for awhile and refreshing oneself.
